Copper Wire Connector Manufacturer Overview
What is a UY connector?
A UY connector is a yellow gel-filled IDC splice connector used to join two supported solid copper telephone wires without stripping the insulation. The IDC contact cuts through the insulation during crimping and makes electrical contact with the conductor, while the gel helps protect the splice from humidity and condensation. The UY connector is the compact model in the yellow UY family, commonly used for copper telephone cable pair splicing, cable fault repair, and high pair-count cable work where a smaller splice bundle is preferred.

Installation
UY connector installation steps
UY connectors are installed by inserting two supported solid copper wires into the connector ports and crimping the yellow cap with a compatible crimping tool or suitable parallel-jaw pliers. No wire stripping, soldering, heat shrink, or tape is required for supported wire sizes.
- Prepare the wire ends: cut the solid copper wires with clean, square ends. Do not strip the insulation.
- Insert the wires: push both wires fully into the connector ports until they bottom out.
- Crimp the connector: press the yellow cap evenly until the connector is fully seated.
- Check the splice: confirm that the connector is closed and the wires are held firmly.
- Tool note: compatible crimping tools can be discussed for bulk or project orders.
Model comparison
UY compared with UY2 and UR connectors
Buyers often compare UY, UY2, and UR connectors because all three are gel-filled IDC splice connectors used in copper telecom wire work. The correct choice depends on wire count, wire size, maximum insulation diameter, and existing model specification.
- Choose UY: compact yellow 2-wire splice for 0.4-0.7 mm wire.
- Choose UY2: larger yellow format when wire size or insulation diameter requires it.
- Choose UR: red connector for two or three wires, or when a red connector is specified.
| Parameter | UY | UY2 | UR |
|---|---|---|---|
| Color | Yellow | Yellow | Red |
| Wire count | 2-wire | 2-wire | 2-wire or 3-wire |
| Wire range | 0.4-0.7 mm / 26-22 AWG | 0.4-0.9 mm / 26-19 AWG | 0.4-0.9 mm / 26-19 AWG |
| Max insulation O.D. | 1.52 mm | 2.08 mm | 1.52 mm |
| Blade/contact | Single IDC contact | Single IDC contact | Dual IDC contact |
| Typical use | Compact pair splicing, smaller wire range | Enhanced yellow 2-wire splice, larger wire range | 2-wire or 3-wire repair and tap splice work |

FAQ
Buyer questions
What is a UY connector?
A UY connector is a yellow gel-filled 2-wire IDC splice connector used to join two supported solid copper telephone wires without stripping the insulation.
What wire sizes does the UY connector support?
The UY connector supports 0.4-0.7 mm / 26-22 AWG solid copper wire, with a maximum insulation O.D. of 1.52 mm. For wire sizes up to 0.9 mm, review the UY2 connector instead.
Is the UY connector gel-filled?
Yes. The UY connector is gel-filled to help reduce moisture exposure around the splice area in suitable telecom field environments.
Is the UY connector waterproof?
The UY connector is moisture-resistant, not designed for full submersion. Final protection depends on wire fit, crimping quality, and the surrounding closure or cable system.
What is the difference between UY and UY2 connectors?
UY is the compact yellow 2-wire splice for 0.4-0.7 mm wire and maximum insulation O.D. of 1.52 mm. UY2 is the larger yellow 2-wire format for 0.4-0.9 mm wire and maximum insulation O.D. of 2.08 mm.
What is the difference between UY and UR connectors?
UY is a yellow 2-wire straight splice. UR is a red connector for 2-wire or 3-wire repair and tap splice requirements.
How do you install a UY connector?
Insert two supported solid copper wires fully into the connector body, then crimp the yellow cap with a compatible tool or suitable pliers until the connector is fully seated. No stripping or soldering is required.
Can Mintel supply UY connectors in bulk?
Yes. Mintel supports factory-direct bulk supply, distributor orders, neutral packaging, and OEM packaging discussion for qualified B2B buyers.
Can I include UY with other connector models in one inquiry?
Yes. Buyers can include UY, UY2, UR, UR2, and UB2A in one inquiry. Share model names, quantities, wire specifications, packaging needs, destination country, and documentation requirements.
